Are the Leftover Soup characters attractive?
Over the years, I've drawn them more and more abstracted and cartoony - the art was worse overall, but the style was more realistic in the beginning, I think. I guess whether or not you consider them attractive depends on how your brain interprets that style. Some people can get more into an abstracted style than others.
Whether or not a character is supposed to be attractive... well, I try to make that clear in the writing, in the way that these characters interact with each other. After all, attractiveness is defined by the ability to attract - even if I drew Ellen with green skin and orc tusks, if the other characters are attracted to her, then she is, by definition, attractive.
Definitely some characters are more visually complicated than others. Carol, Gina after her makeover, Ellen right now... I put more visual detail into their design, more shading and highlights and such. This isn't necessarily meant to indicate prettiness per se, but rather the level of artifice involved.
It's also more work. I hope Ellen gets changed soon.
